We’re having a problem with Let’s Encrypt certificates on an external web server (simon4d.bel.com) where some hosts do not see that the certificate chain is valid. Others do.
Unfortunately, the Gravity Forms server which is at www.bel.com doesn’t. When we run webhooks, we’re getting
cURL error 60: SSL certificate problem: unable to get local issuer certificate (0).
Any ideas how we can get around this?
